Answer 1

Estás usando RVM en lugar del Ruby que viene con 10.8. Bueno. Ahora, deja de usar el MySQL que viene con 10.8.

Instalar y actualizar Homebrew . Ahora corre

brew install mysql

Usa el /Gemfile en tu proyecto para instalar la gema mysql2 . Añadir

gem "mysql2"

a su /Gemfile . Luego actualiza tu aplicación con Bundler ejecutando

bundle install

Permita que los administradores de paquetes (Homebrew y Bundler) trabajen para usted.

Esto debería solucionar los problemas que tienes.

Answer 2

Yo también obtengo el mismo tipo de error en mac10.10 y uso los siguientes comandos que funcionan para mí:

1. Instale y actualice Homebrew usando:

   brew install mysql

2. Ejecute el archivo Install gem Mysql usando:

   joya instalar mysql2 -v ''0.3.11''

3. Ejecutar la instalación del paquete

Answer 3

Como dijo Deefour , tuve que usar RVM. La respuesta va para él, simplemente no pude comentar su respuesta. +1

Pero rvm exec bundle install me dio un error:

rvm do bundle install se eliminó, utilice rvm 1.9.2,1.9.3 do bundle install o rvm all do bundle install lugar.

Utilicé sudo rvm all do bundle install y todo salió perfecto a partir de ese momento.
